My desktop application should update my facebook status. Is there an API that allows updating status using login and pwd?
Thank you in advance for your reply.
Of course have!
.NET FacebookToolKit was made third-party for Microsoft, and then published as open source in CodePlex.
There is proper documentation and even videos on how to make your first desktop application and how to publish stories, status, etc. FaceBookToolKit CodePlex Documentation
There is an API Status.set that allows you to do such things.
